The Ayushman Bharat Scheme, also known as Pradhan Mantri Jan Arogya Yojana (PMJAY), is a health insurance scheme introduced by the Government of India.

Option 1 is correct, there is no cap on the family size or age of the members when it comes to availing the benefits of this scheme. This makes this scheme accessible to any family regardless of its size.

Option 2 is also true. The scheme covers not just actual hospitalization expenses but also takes into account the costs incurred before and after the hospitalization.

Option 3 states that there is a provision of a transportation allowance per hospitalization in the scheme. This is true as a certain amount is provided to the beneficiaries to cover the expenses of transportation.

However, option 4 is incorrect. The scheme provides a benefit cover of ₹5 lakh per family annually, not ₹10 lakh. This cover is provided for secondary and tertiary care hospitalization. Thereby, the correct answer is 4.
